' 3Claims. (01. 296-445) This invention relates to improvements in window runways or window channel, such as are used in automobile bodies for guiding the slidably mounted, sashless glass windows thereof. More 5 particularly, the present invention relates to the window-cushioning linings of such runways or channel.

The general object of thepresent invention is the provision of a window runway or channel having an improved window-cushioning lining, said lining being of simple and inexpensve construction, of such character that it retains throughout its unusually long life its original, exceptionally great resiliency or cushioning efiects, and whichv l6 lining does not impede, even'when wet, the slidable movements of the window therealong.

A more specific object of the present invention is the provision of a window runway or channel having awindow-cushioning lining formed '20 of bristles, such as hogs bristles, held together in mat-like form by coagulated latex, an adhesive which does not impair the inherent resiliency or springiness of said bristles. If desired, said bristles may be provided with a window-engag- 95 ing fabric cover.

Further objects of the present invention are in part obvious and in part will appear more in detail hereinafter. 1

i The invention will be readily understood from the following description thereof, reference being had to the accompanying drawing in which Fig. 1 is a perspective view of a portion of tire improved lining of the present window runway or channel, said portion comprising a layer or mat 36 of entwined or entangled hogs bristles held together in such layer-like or mat-like form by liquid latex; Fig. 2 is a similar view ofsaid layer or mat of bristles provided with a window-engaging fabric cover; Fig. 3 is aperspective view of a 40 portion of the present runway or channel in finished form; and Fig. 4 is a sort of microscopic view of a portion of the entwined or entangled hogs bristles of the present improved runway or channel lining, showing the manner in which said bristles are bound or tied together by the coagulated latex. The window runway or channel here illustrated and described is particularly suitable for use in guiding the slidably mounted,.sashless glass windows of automobile bodies, said runway or channel comprising a suitable channel-Shapedsttucture, of metal or the like, and a suitable windowengaging lining therefor, said lining being of sufflcient resiliency to properly cushion the windowagainst the shocks and jars to which it is usually September 6, 1932, or in the Gaines .Patent No. 1,898,948, granted February 21, 1933, the purpose of said slots being to give said member increased flexibility, as pointed out in said patents and as will be readily understood.

For cushioning the window which said channel shaped structure receives in use thereof, a suitable resilient lining is provided therefor, said lineing being longitudinally secured within said structure by the side wall beads l2 thereof, as clearly shown inFig. 3.

'The present improved lining for said channel shaped structure includes a layer or mat I5, of ,entwined or entangled hogs bristles bound .or

tiedatogether, one to another, in such layer-like or mat-like form by coagulated latex, an adhesive which doesnot impair the inherent resiliency or springiness of said bristles. In 4, a sort of microscopic view of said entwined or entangled bristles is shown, said bristles, indicated by the reference character l8,-being held in such entwined or entangled form by said coagulated latex, indicated by the reference character [9.

In forming this part of the present improved lining, the bristles l8 are arranged in layer-or mat form, and the liquid latex is then sprayed thereon, in sumcient quantity to substantially permeate the entire-layer or mat of bristles'and when dry to effectively bind or tie said-bristles together in such layer-or mat form;

In the embodiment of the invention here shown,

said layer or mat of bristles is provided with a suitable window-engagingcover II, of felt or other suitable fabric, said cover having its longitudinal edge portions 23 bent or turned around the corresponding edge portions of said layer or mat of bristles, as best shown in Fig. 2.

As shown in Fig.3, the present improved lining, comprising the layer or mat of bristles and the fabric cover 2! therefor,-is longitudinally arranged in the channel shaped structure of the 5 present runway or channel, said lining assuming in cross section a channel shape corresponding to that of said structure. The longitudinal edge 10 shown in my priorPatent- No. 1,876,519, granted v portions of saidlining are clamped within the longitudinally disposed beads I! of said structure side walls II, the inner surfaces of said beads lying outside of the planes of the window-engaging surfaces of said lining side walls-. If desired and as shown, said lining may be provided with longitudinal stitching II at its two fold lines, said lines lying adjacent the junction of the base l and the side walls ll of said channel shaped structure;

Due to the improved lining with which it is provided, thepresent window runway or channel is capable of receiving and'guiding windows of abnormal thickness, the bristles of said lining affording throughout theirexceptionally long life a resiliency or springiness which effectively protects all windows from the shocks and Jars to which they are subjected in use. v Further features of the present invention will be apparent to those slrilled in the art to which it relates.

What I claim is:

generally channel-shaped structure having a baseand a pair of window-receiving side walls, anda window-cushioning resilient lining for said structure, said lining being formed of coarse inherently resilient bristles loosely entangled in matlike form of substantially uniform density.

2. A window runway or channel, comprising a generally channel-shaped structure having a base and a. pair of window-receiving side walls, and a window-cushioning resilient lining for said structure, said lining being formed of coarse inherently resilient bristles adhesively held together, by the rubber of a latex solution, in loosely en- 1. A window runway or channel, comprising a tangled mat-like form of substantially uniform density. I

3. A lining for window runways or channels formed of coarse, inherently resilient b'ristles which are loosely entangled, said bristles being held together in mat-like form by an adhesive in sufllcient amount to bind the bristles together but in an 'insuflicient amount to impair the inherent resiliency of said bristles.
